Achilles Tendonitis The Facts

Overview
Achilles tendinitis is an overuse injury of the Achilles (uh-KIL-eez) tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. Under too much stress, the tendon tightens and is forced to work too hard. This causes it to become inflamed (that?s Achilles tendinitis), and, over time, can produce a covering of scar tissue, which is less flexible than the tendon. If the inflamed Achilles continues to be stressed, it can tear or rupture. Achilles tendinitis most commonly occurs in runners who have suddenly increased the intensity or duration of their runs. It?s also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends. Most cases of Achilles tendinitis can be treated with relatively simple, at-home care under your doctor?s supervision. Self-care strategies are usually necessary to prevent recurring episodes. More-serious cases of Achilles tendinitis can lead to tendon tears (ruptures) that may require surgical repair.

Causes
Hill running or stair climbing. Overuse resulting from the natural lack of flexibility in the calf muscles. Rapidly increasing mileage or speed. Starting up too quickly after a layoff. Trauma caused by sudden and hard contraction of the calf muscles when putting out extra effort such as in a final sprint. Achilles tendinitis often begins with mild pain after exercise or running that gradually worsens.

Symptoms
The most common site of Achilles Tendonitis is at the heel to 4 inches above the heel. The diagnosis of this problem is made when the following signs are present. Pain in the Achilles tendon with up and down movement of the foot at the ankle. Pain in the Achilles tendon when you squeeze the tendon from side to side. If you are unable to move the foot either up or down, or you have intense pain when trying to walk, you may have a tear of the Achilles tendon, and you should see a doctor immediately. Also if you have severe pain in the calf, with or without discolorations of the skin, you may have a blood clot, and this is a medical emergency; see a doctor immediately. If you do not fall into either of these categories then try the following suggestions.

Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.

Nonsurgical Treatment
If you have ongoing pain around your Achilles tendon, or the pain is severe, book an appointment with your family physician and ask for a referral to a Canadian Certified Pedorthist. Your Pedorthist will conduct a full assessment of your feet and lower limbs and will evaluate how you run and walk. Based on this assessment, your Pedorthist may recommend a foot orthotic to ease the pressure on your Achilles tendon. As Achilles tendinitis can also be caused by wearing old or inappropriate athletic shoes for your sport, your Pedorthist will also look at your shoes and advise you on whether they have appropriate support and cushioning. New shoes that don?t fit properly or provide adequate support can be as damaging as worn out shoes.


Surgical Treatment
Surgery is an option of last resort. However, if friction between the tendon and its covering sheath makes the sheath thick and fibrous, surgery to remove the fibrous tissue and repair any tears may be the best treatment option.

Prevention
Suggestions to reduce your risk of Achilles tendonitis include, icorporate stretching into your warm-up and cool-down routines. Maintaining an adequate level of fitness for your sport. Avoid dramatic increases in sports training. If you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse. Wear good quality supportive shoes appropriate to your sport. If there is foot deformity or flattening, obtain orthoses. Avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury. Maintain a normal healthy weight.
